The collective symptoms are consistent with a distributed denial-of-service attack. ECIH network-incident handling requires responders to correlate traffic volume, resource consumption, connection patterns, and distributed source information when validating DoS/DDoS activity. Here, bandwidth saturation, elevated router CPU utilization, overloaded NAT tables, excessive connection attempts, and traffic originating from multiple geographic locations collectively indicate coordinated resource exhaustion. A vulnerability scan can generate connections to multiple ports, but it ordinarily does not produce the widespread bandwidth and infrastructure exhaustion described. Data exfiltration is associated primarily with unauthorized outbound transfer of information rather than massive incoming traffic. A rogue DHCP server affects address assignment and network configuration but does not explain geographically distributed request floods. The distributed sources and resource-exhaustion effects therefore make a DDoS incident the strongest diagnosis.

Yesware is a tool primarily known for its email tracking capabilities, which can be useful for sales, marketing, and customer relationship management. However, in the context of investigating email attacks and analyzing incidents to extract details such as sender identity, mail server, sender’s IP address, and location, a more appropriate tool would be one that specializes in analyzing and extracting detailed header information from emails, providing insights into the path an email took across the internet. While Yesware can provide data related to email interactions, it might not offer the depth of forensic analysis required for incident investigation. Tools like email header analyzers, which are designed specifically for dissecting and interpreting email headers, would be more fitting. In the absence of a direct match from the given options, the description might imply a broader interpretation of tools like Yesware in context but traditionally, tools specifically designed for email forensics would be sought after for this task.

The ECIH Risk Assessment and Recovery module stresses that recovery must not reintroduce threats. When backups may be compromised, validating their integrity is critical.

Option A is correct because scanning backups with updated signatures and heuristic analysis ensures that latent malware is detected before restoration. ECIH emphasizes that restoring infected backups can trigger reinfection and negate eradication efforts.

Option D is excessive and disruptive. Option B is a containment control, not a recovery safeguard. Option C risks reintroducing compromised data.

Therefore, validating backups before restoration is the priority recovery action.

This scenario represents deceptive phishing because the attacker impersonates a trusted internal authority and directs employees to a fraudulent login page designed to harvest credentials. ECIH v3 email incident handling emphasizes examining sender information, URLs, domains, email headers, and landing pages when investigating suspected phishing. The fake HR message uses social engineering and a look-alike web page to persuade users to disclose payroll or authentication information. Email spamming refers broadly to unsolicited bulk messages and does not necessarily involve targeted credential theft. A mail storm is an abnormal flood of email traffic, while DNS cache poisoning manipulates DNS resolution rather than using a fraudulent link in an email. Elena ' s preservation of headers, screenshots, and malicious-domain information also follows appropriate evidence collection and containment practices for phishing incidents.
